The distribution of soil particles and planting tube space position affects reversal cultivated land and fertilization seeder seeding performance. Through the establishment of ratary tiller system coordinate system; Firstly giving the analysis of soil grain not heel cover shell collision and the first meeting with cover shell collisions motion situation, through Matlab found the first meeting w...

the chisel plow is one of the tillage implements utilized to carry out conservation tillage practices; therefore, it is valuable to pay more attention on the force requirement of this implement. to achieve this goal, a theoretical model was developed to calculate draft, specific draft, and drawbar power of a chisel plow. then, results obtained from the developed model were compared with the rep...

drafts of major primary tillage implements were measured in a clay loam soil using a tension loadcell. implements consisted of a moldboard, a disk and a chisel plow each equipped with one tillage unit. a photoelectric speed sensor was used for actual forward speed measurements. during the study, the effects of forward speed and tillage depth on draft requirements were investigated. a general re...

The authors showed that a rotary plow deepened the arable layer and destroyed bottom, simultaneously crushed plant residues, green manure crops embedded them in soil upper was active for cultivated plants roots microorganisms, which allowed providing with available nutrients, maintained fertility increased soybeans yield. ( Research purpose ) To determine deepener rotor agrotechnical parameters...
